Bitumen Product Description : Bitumen is widely used in the construction of asphalt roads and bituminous membrane products. Bitumen is commonly used to build highways, motorways and rail networks. Bitumen has excellent water-proofing properties and is widely used for making roofing products along with a range of other household and industrial applications, from emulsion paints to sound-proofing. Penetration Bitumen and Bitumen Emulsions are used for the construction of railway tracks and by using special types of bitumen such as Polymer Modified Bitumen, the vibration and noise levels are reduced due to a dampening effect. Bitumen has been proven to be effective on both high-speed railway tracks and heavy load railway tracks. Bitumen is also used for surfacing airfield runways and air strips (PMB is preffered due to its fuel resistant properties) and taxi ways. For the Marine construction industry bitumen is used for hydraulic applications such as canal lining, underwater tunnels, river bank protection, dam construction and sea defences. There are also numerous industrial applications like roofing felt material, printing inks, packaging paper, linoleum, electrical cable / Junction box insulation, mastic for roofing of terraces, and duplex paper manufacture.
